<^>PROBLEM!<^> 2015 Jeep Grand Cherokee SRT Head unit upgrade uConnect 8.4

Today I swapped out my factory head unit and media hub. It had the Non-CarPlay and Non-AndroidAuto model. I bought the upgraded model with media hub to update my gear. After install today, all it does it power-cycle. It will turn on (saw it update factory apps) and at about the 1 minute mark, it restarts. I let it do this for about 2 hours. I was searching on what to do. Some say to pull the fuse, and let it sit about 5 minutes, some say disconnect the battery for 5 minutes, so on and so forth.
I did that. Disconnected radio from power source. Waited 15 minutes, no luck. Disconnected battery for about an hour, no luck.

Anyone know what to do?
